the invent-ion, such as will enable othersl skilled in the art to which it appertains to make and use the same.

This invention is a concrete railway tie,

and the invention pertains more parti ularly to an improved construction and a angement of the internal reinforcing of the concrete tie, in combination with a tie plate or rail cushion that coperates with the internal reinforcing of the tie to prevent wear on the tie or crumbling of the concrete.

With these and certain other objects 1n View which will appear later in the specification, my invention consists in the devices described and claimed and the equivalents thereof.

In the drawings, Figure 1 is a parthorizontal section of a tie embodying my im-4 provement.

Fig. 2 is a part sectional side elevation.v Fig. 3 'is' a detail of one forni of railfastening device. Fig. 4 is a part sectional detail .of a tie and rail with the rail-fastening in Fig. 3 in place.

Fig. 5 is a perspective view of one formv of rail cushion. A

Fig. 6 is a part sectional perspectiveof a modified form of railcushion and railfas tening. Fi

fied um of cushion shown in Fig. 6.

Fig. 8 shows a modified form of rail-fastening plate that also serves as a rail brace. Fig. 9 is a part vertical lon 'tudinal section through the end of'a tle showing a modified arrangement for the nest of reinforcing material.

As is clearly shown in the drawings, -the railway tie consists of two concrete tie members 1 and 2, which may be fastened together along the center line of the railway track by means of tie bars 3 and bolts 4, or their equivalents.

In carrying out my invention, I reinforce am ne members 1 and eby embedding in them strips of expanded metal 5, the strips being set on edge and preferably extending illustrated i the tie.

7 is a perspective detail of the modifrom the top surface of the tie member down to the bottom of the member, or nearly to the bottom. The strips 5 ma be bent in any suitable manner, but I pre er the arrange-y ment shown in Fig. 1, in which one of the strips 5 extends along one side of the tie member and part way across its end, and the opposite strip 6 similarly extends along the outer side of the tie member, so that the twostrips together partly inclose the body of the tie near its outside.

The outer ends of the reinforcing may be folded back upon themselves as at 7 in Fig. 1, or if desired the ma be bent so as to extend across the en of t e tie as at 8.

In that part of the tie that supports the layers of expanded metal set on edge. These layers may be arranged as shown in Fig. 1

by bending a strip of expanded metal back and forth upon itself to. form a nest 9 embedded in the body of the tie. They may also be arranged in any other suitable manner with the planes of the meshes vertical, as

for illustration, with the bends of the strips at the top and bottom as shown in Fig. 9.

The purpose of the reinforcing strips 5 and 6 and of the nest of strips 9 is to rein. force the concrete against crumbling and disintegrating at the point where such action is most likely to occur on account of 'the vibration ofthe rails when trains pass over I further strengthen'and reinforce the end 9 of the tie by means of a rail-fastening and rail cushion or tie plate.

In the form shown in Figs. 3,4 and 5, the tie plate or cushion consists in 'a flat plate 10 having downwardly extending flanges 11 engaging the sides of the tie member 1. The l flanges 11 may be formed with slots 11A if desired, to impart additional resilience tn the tie plate 10.

Bolts 12 pass through the tie from side to side to secure the flanges 11 in place. The bolts also serve to clamp the rad-fastening plates 13 to the flanges 11, the fastening plates being formed with openings 14 to receive the bolts 12.

The upper edge of each fastening plate 13 is provided with a hooked member 15 adapt ed to take over the edge of the rail flange 16 as shown in Figs. 1, 2 and 4. The fastening plate may be formed if desired with a hooked member, as shown in Fig. 8 adapted to extend to and engage the we of the rail,

and serve as a rail lbrace. This constructionqtit is apparent that any equivalent of exis desirable for use on curves. l

lt will be noted that the bolts 12 and the anged tie plate assist in sustaining the nest 9 of reinforcing material and in reducing the liability of the concrete crumbling when subjected to repeated impacts.

In the modified form of cushlon shown in Figs. 6 and 7 the plate is formed in two parts, each of which comprises a horizontal member 17 and a vertical flange 1 8, the flange being perforated to receive bolts 19 that pass through the tie from side to side.

With this form of cushion 'platethe rail` fastening plates 13 shown in Fig. 4f may be used, or if desired, the rail flange 16 may be held in place by means of suita le clips riveted or otherwise secured to the horizontal plate members 17 of the rail cushion, as shown in Fig. 6, where clip 20 is riveted to the horizontal member of onehalf of the two-part cushion and the opposite .clip is riveted to the other half of the cushion, to enablethe two halves of the cushion with their clips attached, to be readily assembled on the tie. c

When the plate 10 and its Hanges 11 are formed in one piece, as shown in Fig. 4, the

bolts are inserted 'after the plate has been put inplace, holes having been left in the tie to receive the bolts.

, ln' the form of cushion shown in'Fig. 6, the bolts may be embedded in the concrete tie with their ends projecting and the twopart plate 17 may be assembled on the tie alfter it has been molded with the bolts in.

P f Y While I have described the reinforcing material as being made of expanded metal,

panded metal, such as metal fabric of any suitable character, could be used without departingIl from the spirit of my invention.

By t e means above described, l have produced a concrete tie which is strongl reinforced in that partwhich is direct y subjected to the pounding action of the rail, the cushion and the rail-fastening 'device cooperating with the reinforcing to' prevent crumbling of the tie. Having thus described my invention, what I claim and desire to secureby Letters Pat ent is:

1. In a concrete railway tie, a reinforcing device comprising a strip of metal fabric folded repeatedly back and forth u on'itself, with the layers arranged vertica ly and spaced apart and embedded in the concrete beneath the rail-supporting part of the tie.

2. In a concrete railway tie, a reinforcing device comprising strips of metal fabric embedded in the concrete beneathV the rail-sup porting part of the tie, said strips folded re eatedly back and forth upon themselves, wlth the layers arranged vertically and spaced apart, a rail-fastening'and tie-clamping plate carried by said tie above said reinforcing strips, and bolts extending through the plate, tie and reinforcing strips, and

- means for tightening said bolts to clamp said t plate to said tie, for the purposes set forth.

In testimony whereof, I afix my signature in presence of two witnesses.
